The VLFeat open source library implements popular computer vision algorithms including SIFT, MSER, k-means, hierarchical k-means, agglomerative information bottleneck, and quick shift. It is written in C for efficiency and compatibility, with interfaces to MATLAB for ease of use, and detailed documentation throughout.

VLFeat supports Windows, Mac OS X, and Linux, and bundles binaries for all these platforms. VLFeat is ready out-of-the-box.

VLFeat is the recipient of the ACM Multimedia Open Source Award 2010.
